5 Claims.

My invention relates to improvements in mail enclosures or folders and more particularly, has reference to and is illustrated in the accompanying drawings as applied to a return mail folder especially adapted for use by public service cor.- poraticns in billing service and for return remittance. Y

Referring to said drawings, Fig; 1 illustrates in plan view one side of a preferred form of folder embodying an application of my invention. Fig. 2 is a similar view of the reverse side thereof. Fig` 3 is a perspective view of the same 'being folded for original mailing, and Fig. 4 asimilar view of the same being folded for return mail.

One side of the folder is provided with foldable panels 5, 6 and 1. The panel 5 is for the bill, the panel 6 is for the return address of the service company and the panel 'I is blank. i The panel 6 a pair `of under glued foldable end flaps 8 and il', and the panel 1 is provided with a pair of over glued foldable end flaps 9 and 9' and an over glued flap l0 along its free long side; The numeral ll indicates a foldable duplicate bill stub which may be returned with the bill to be receipted or may be torn off and retained as may be found desirable.

In Fig. 2 the blank is shown from reverse side and in upside down position. This side l of the plain panel l contains the name and address of the customer, with flaps 9, 9 without glue on the now exposed side. The now exposed side 6 of the center. panel 6 is plain, with glue on the exposed sides of the flaps 8, 8' while the end panel 5 has printed or advertising matter as shown and the same applies to the now exposed side Il of the stub Il.

Referring now to Fig. 3, it will be observed that the stub il has been turned in over the bill panel 5, and likewise the aps 8, 8 over the panel 6, containingthe service company address. When the panel 5 has been laid down on panel 6, the other end panel l, 'l' is laid over the same, the end flaps 9, 9 being turned under the plain back B of the center panel 6 where they are glued fast, and the long side flap I may then also be tucked in, leaving only the customers address exposed on panel 'l' for mailing, with the folder sealed so that any desirableloose printed matter may be inserted, even with the flap i0 unsealed, only second rate postage being required in the latter contingency.V

Upon receipt of the mail, the end flaps 9, 9' may be slit or out clear and the folder opened. For returning the mail, the stub I i, Il may be y removed or may be folded in on the panel the lov `glue on the surface -bearing an address,

latter being folded over on panel 6. The end panel l' may now be folded upon the bill panel 5, and the flaps 5, 8 may be folded in between panels 5 'l'. unless they have already been removed. The end naps 8, 8', and long side flap I0 may now be secured to the' exposed panel 6, and the whole may now be mailed with inserted check or cash as may be found desirable.

Of course it will be understood that various modifications may be made in the construction and arrangement of parts without ldeparting from the spirit of the invention as claimed.

I claim:

1. A return mail folder, comprising a blank having three adjacent foldable substantially congruent panels having the addresses of the addressor and addressee on the reverse sides of adjoining panels, said remaining panel being irnprinted with a bill form and having a stub extending laterally `from one side thereof, said addressor and addressee panels having a foldable flap formed on each lateral end thereof, said flaps for each of said panels being provided with opposite the panel. surface whereby may be used to seal said folder when folded to expose one of said addresses and the other pair of flaps may be used to seal said folder when folded vto expose the other of said addresses.
